Question

Ravi was performing some experiments related to the laws of chemical combination in his
science laboratory under the guidance of his chemistry teacher Mr. John. Mr.John gave him
different samples of reacting species having different masses. Ravi performed the experiments
and collected data as :
SL.NO Compounds Reactant species Masses of reactant
species(g)
1 H2O H 1
O 8
2 CO2 C 12
O 32
3 NH3 N 14
H 3
1. Calculate the mass of carbon dioxide gas formed.
2. In a given sample ammonia contains 3g of hydrogen and 14g of nitrogen. If another sample
contains 5g of nitrogen then how much amount of nitrogen present in second sample?
3. Which law of chemical combination govern these experiments?
4. State the law.

Answer 1

Answer:

It is because of law of chemical combination of reaction which states that weight of products and reactants will be same.

And no atoms, molecules and weight is lose.
